Patent GB-1028417-A (GB)
Title: Photovoltaic cell with high output
IPC: H01L31/054
Filed: 1963-06-07
Abstract: 1,028,417. Semi-conductor devices. SOC. EUROPEENE DES SEMI CONDUCTEURS. June 7, 1963 [June 8, 1962], No. 22782/63. Heading H1K. A photo-voltaic cell is made from a monocrystalline wafer of semi-conductor material which contains at least one rectifying junction and which has its two major faces effectively inclined with respect to one another, this being achieved either by wholly inclining the faces or by inclining elements of one or both major faces. The angle of inclination is made such that radiation incident normally on the entry surface undergoes a series of total internal reflections at the insides of the two major faces. The angle of inclination may be halved provided that one major face is given a metallic coating so that the first reflection occurs at a metallic surface. Because of the long radiation path length produced in the body, radiation having an energy only slightly above the band gap energy of the semi-conductor may be readily absorbed. Each of the specific embodiments has one plane major face. In one (PN) the second face is inclined in its entirety; in a second (PN) a series of parallel grooves of saw-tooth section are formed on the second face; in a third (PIN) the second surface takes the form of a hollow cone; in a fourth (PN) the second face is formed by two mutually inclined planes which make equal angles with the first major face; and in the fifth (PN) the second face is etched to cover it with pyramids formed by selective attack on the various crystal planes. The semi-conductor material may be silicon. The etchant used in forming the fifth embodiment is a specified mixture of hydrofluoric acid, nitric acid, acetic acid, and bromine.

Title: Supercharging systems of rotary-piston diesel engines
IPC: F02B29/04
Filed: 1971-04-19
Abstract: 1331348 Supercharge I.C. engines; treating charge; cooling SOC ANON DE VEHICULES INDUSTRIELS ET D'EQUIPEMENTS MECANIQUES SAVIEM 19 April 1971 [9 March 1970 10 Feb 1971] 23571/71 Heading FiB In a supercharging system of a rotary-piston, water-cooled diesel engine having an exhaust gas driven turbosupercharger 16, Fig. 1, an air/ water heat exchanger 17 and a volumetric supercharger 11 in series, the supercharger 11 is driven proportionally to engine speed and part of the supercharging air is discharged from the connection between the supercharger 11 and the engine 1 to modify the supercharging pressure as a function of engine power output. The engine crank-shaft 3 carries a flywheel 9 with balance weight 10 and the slow rotor 11' of the Planche type with a balanceweight 12 (the fast rotor is not shown). A charge treating system may add a preliminary fuel/air mixture at 23. The heat exchanger 17 is connected to the engine cooling water radiator 29. At low power outputs all the supercharging air is supplied to the engine 1 since the orifice 40 at the end of passage 21 is closed to prevent any air divertion. Orifice 40 is controlled by a spring-loaded needle valve 41 of tapered or curved shape, responsive to a bellows 44 the interior of which is responsive to the turbosupercharger delivery pressure. With increasing power output the orifice 40 is progressively opened so that an increasing amount of supercharging air is diverted through passage 21 a heat exchanger in the turbine exhaust passage and orifice 40 thereby inducing increasing air flow through radiator 29. In another embodiment the air passes through a turbine exhaust gas/air heat exchanger (72), Fig. 5 (not shown) to a nozzle 88 thereby accelerating the exhaust gas flow, the latter being used in a pump 99 to increase the cooling air-flow in the radiator 79. In a modification of this embodiment the nozzle 88 is replaced by an annular nozzle (83) Fig. 5 (not shown). The volumetric supercharger may be a rotary lobed piston type.

The end of the inner sheath 11 protruding beyond the extension piece 19 has a hood 24 attached to it by means of a channelled annular connecting piece 23. The hood 24 enshrouds the extension piece 19 and at its lower end carries a fitting 25 which engages the extension piece 19 at circumferentially equispaced locations between which are openings for coolant entry. The hood 24 forms with the vent clearance 20 a lute or diving bell gas trap. A downwardly projecting skirt 23a of the connecting piece 23 carries a thin stainless steel cup seal 26 with a down-turned inner rim forming a lip resiliently engaging the extension piece 19. The fuel element illustrated is intended for use in a fuel assembly, the spacing of the fuel elements clustered together in such an assembly being maintained by a wire 36 wrapped in a helix around each of the fuel elements. A plurality of cup seals in series may be used, possibly in a nested arrangement.

Abstract: 406,059. Centrifugal dust extractors. ANGUS, T. C., Banks Farm, Lambourne End, near Romford, Essex. Aug. 29, 1932, No. 24060. [Class 23.] Solid particles are extracted from fluid in a rotating chamber into which the fluid is injected with a circumferential velocity substantially equal to the velocity of the chamber. The chamber 10 is closed at the top and secured to the shaft 12, while its lower end is partly closed by a plate 14 fixed to a discharge pipe 15. The inlet pipe 16 passes through the discharge pipe and it terminates inside the chamber 10 in a number of nozzles 17 arranged so that the direction and velocity of the entering fluid enable it to enter without turbulence. The separated dust settles on the wall of the chamber 10 and the clean air passes'through the pipe 15 which has a flared top. The dust falls when the machine is stopped or is removed by mechanical scrapers, air or water jets. In the modification shown in Fig. 3, the inlet pipe 19 enters at the top of the chamber 10, and a number of vanes 22 of straight or helical form assist in rotating the fluid. In a further modification the nozzles 17 are replaced by radial vanes in the upper part of the chamber which rotate immediately below the fluid inlet.
